G0 and G1 cameras are very compact, lightweight and easy to operate. The user only needs to insert it into telescope focuser, plug the USB cable to the computer and it works.

Sensitivity is an important feature of any guider. It must provide images of guiding star(s) with sufficient S/N ratio in rather short time to ensure perfect guiding. The necessity to accumulate light for many tens of seconds or even minutes is often unacceptable for high quality guider. This is why the G1 cameras utilize sensitive Sony ICX CCDs.

Both G0 and G1 series of CCD cameras contain similar electronics, same CCD detectors and provide similar functionality. The difference is mainly in mechanical construction and in cooling.

G0 cameras offer round body, which is more compact compared to G1 series, which could be important e.g. in combination with Off-Axis Guider etc.

G1 cameras are slightly bigger and heavier, but they keep the CCD detector on lower temperature thanks to embedded fan, which more than two times lowers detector dark current. They also offer CS-thread adapter and also other alternatives of lens adapters (Canon EOS and Nikon bayonets, T-thread etc.).
